Leak Detection Sensor EM300-SLD/ZLD

EM300-SLD Spot Leak Detection Sensor – lorawan® Smart Water Leakage Monitor with TH Sensing

The Milesight EM300-SLD is a compact, ultra-durable lorawan® spot leak detection sensor designed to detect the presence of water or other conductive liquids in high-risk environments. Utilizing a stainless steel probe and a highly sensitive 5 mm trigger threshold, the EM300-SLD transmits instant alerts to notify users of leakage events. It also features integrated temperature and humidity sensors for environmental monitoring, making it ideal for applications like pipe leak detection, basement flooding prevention, and HVAC system oversight. With a robust IP67 enclosure, up to 10 years of battery life, and support for Milesight D2D communication, it is purpose-built for harsh industrial and commercial deployments.
